Jmeter simulates different bandwidths for testing

Jmeter comes with analog bandwidth settings, provided that the current bandwidth > = the bandwidth to be simulated, for example, the current 4m broadband can only simulate the bandwidth of 4m or less.

Setting method: in the user.properties file, add the following configuration:

# Define characters per second > 0 to emulate slow connectionshttpclient.socket.http.cps=49152httpclient.socket.https.cps=49152

Above, a bandwidth of Mobile data EDGE: 384kbit/s is defined.

Calculating cps Formula

Cps = (target bandwidth in kbps * 1024) / 8
